Execute db:migrate and db:setup rake tasks inside a controller using jruby and warble

Question

I'm creating an app that must allow the non-programmer end user to install the application by himself.

I already handled the ruby env + web server + database installation part. Now I have to be able to setup the database for the app. I'm thinking about running rake db:setup inside a InstallationController (which will be only accessible during the installation process).

Is it possible? How can I do that?

I'm planning to use Warble and JRuby, so I won't be able to do it by using the command-line inside my app.

As long as the database exists (or creates on use like sqlite3) you can throw an initializer in your app to run the migrations pretty easily.

ActiveRecord::Migrator.migrate(Rails.root.join('db','migrate'))
